The special will feature interviews from friends and acquaintances of the actor including Daniel Baldwin, Bret Michaels, Heidi Fleiss and "a handful of talkative ex-girlfriends".

"I think the chances of Charlie injuring himself or someone else are pretty high," said Baldwin, according to a preview. "There are people openly talking about [how he] will he die soon. Knowing Charlie, probably not. But does that mean that someone else isn't gonna get injured or die or something else horrible isn't gonna happen?

"When I watch what's happening with Charlie right now, I'm very, very sad. This is someone that I've known for almost 25 years. Such a public disintegration is - is very difficult to watch."
